Description
Technical field
This utility model is related to subgrade case technical field, specially a kind of combined high-speed highway road with location structure
Base case.
Background technology
Subgrade case used in Practical Project is made up of a skeleton body now, and skeleton body is by longitudinally elongated riser and horizontal stroke
To riser composition, and oblique riser is set at elongated riser and each horizontal riser, the upper and lower surface of skeleton body is then respectively sealed
There is one layer of cover plate.The planar dimension of generally subgrade case is 3000mm × 6000mm, its top have acting surface be 3000mm ×
The load of 2000mm, the load that top is applied is carried out load sharing by subgrade case, the load intensity of thus obtained top effect with
The ratio of the load intensity after structure load sharing is referred to as intrinsic standoff ratio.So intrinsic standoff ratio also is understood as subgrade case and load is divided
Loading capability.However, monolayer subgrade case weak point in actual use to be exactly load sharing energy Dipeptiven low, its intrinsic standoff ratio maximum is
3:1, it is not applied for the very big engineering of load.
Express highway roadbed case is the very big engineering of load, and traditional base board list used by express highway roadbed case
Body, between stability poor, low intensity it is therefore desirable to improve.
Utility model content
The purpose of this utility model is to provide a kind of combined high-speed highway subgrade case with location structure, to solve
The problem proposing in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme：A kind of combination type with location structure is high
Fast highway subgrade case, including riser, is respectively equipped with the first transverse slat and the second transverse slat on the right side of the top left hand of described riser and bottom,
The structure of described first transverse slat and the second transverse slat is identical, and described first transverse slat and the second transverse slat are highly the one of the height of riser
Half, described riser, the first transverse slat and the second transverse slat composition base board monomer.
Preferably, the lower end of described first transverse slat opens up fluted, and the upper end of described second transverse slat offers and groove one
One corresponding projection.
Preferably, described groove is triangular groove.
Preferably, described groove is at least provided with five, and groove is equidistantly linearly to arrange.
Preferably, the matrix of described first transverse slat offers the first screwed hole, the inside of described first screwed hole is installed
There is self-tapping screw, the matrix of described second transverse slat offers second screwed hole corresponding with self-tapping screw.
Preferably, the top of described self-tapping screw is located at the inside of the first transverse slat.
Compared with prior art, the beneficial effects of the utility model are：The combined high-speed highway of location structure should be carried
Subgrade case, forms mutual locking mechanism, good fixing effect between base board monomer, improves stability, has very strong being suitable for
Property, suitable large-scale promotion.
Brief description

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-2, this utility model provides a kind of technical scheme：A kind of combined high-speed with location structure is public
Road subgrade case, including riser 1, is respectively equipped with the first transverse slat 2 and the second transverse slat 3 on the right side of the top left hand of described riser 1 and bottom,
Described first transverse slat 2 is identical with the structure of the second transverse slat 3, and described first transverse slat 2 and the second transverse slat 3 height are the height of riser 1
The half of degree, described riser 1, the first transverse slat 2 and the second transverse slat 3 composition base board monomer.When base board monomer is combined,
Second transverse slat 3 of a base board monomer is pressed in and forms subgrade case on the first transverse slat 2 of previous base board monomer afterwards, forms phase
Mutually locking mechanism, good fixing effect, improve stability.
Specifically, the lower end of described first transverse slat 2 opens up fluted 4, and the upper end of described second transverse slat 3 offers and groove
4 one-to-one projections 5.Second transverse slat 3 of a base board monomer is pressed on the first transverse slat 2 of previous base board monomer afterwards
When, groove 4 and projection 5 cooperation grafting, improve fixed effect.
Specifically, described groove 4 is triangular groove.Groove 4 groove is triangular groove, coordinates grafting with projection 5, enters
One step improves fixed effect.
Specifically, described groove 4 is at least provided with five, and groove 4 is equidistantly linearly to arrange.Multiple grooves 4 and projection 5 are joined
Close grafting, further increase fixed effect.
Specifically, the matrix of described first transverse slat 2 offers the first screwed hole 6, the inside peace of described first screwed hole 6
Equipped with self-tapping screw 8, the matrix of described second transverse slat 3 offers second screwed hole 7 corresponding with self-tapping screw 8.By boring
Tail screw 8 is fixing, improves fixed effect.
Specifically, the top of described self-tapping screw 8 is located at the inside of the first transverse slat 2.Improve aesthetics, prevent from boring simultaneously
Tail screw 8 damages tire.
The combined high-speed highway subgrade case of location structure, when base board monomer is combined, Hou Yige road should be carried
Second transverse slat 3 of substrate monomer is pressed in and forms subgrade case on the first transverse slat 2 of previous base board monomer, forms mutually locking knot
Structure, good fixing effect, improve stability, improve the load of subgrade case；Second transverse slat 3 of a base board monomer is pressed in afterwards
